5.8 A liquid storage system is shown below. The normal oper- ating conditions are 71 = 10 ft3/min, = 5 ft3/min, = 4 ft. The tank is 6 ft in diameter, and the density of each stream is 60 lb/ft3. Suppose that a pulse change in ql occurs as shown in Fig. E5 8 (a) What is the transfer function relating H' to Q' ? (b) Derive an expression for h(t) for this input change. (c) What is the new steady-state value of liquid level h? Repeat (b) and (c) for a change in qi from 10 to 20 (at
